1! '0 (all whom it may concern:

Be it known that l, DANIEL BRIG-GS, citizen of the United States, and resident of the borough of Brooklyn, city of New Yorl-z, in the county of Kings and State of New York, have invented certain new and useful Inn proveinents in Type-"Writing llfachines, of which the following is a specification.

My invention relates to typewriting inaehines and more particularly to billing mechanism therefor.

One of the objects of my invention is to provide siu'iple, cheap and efficient mechanism of the character specified.

Another object of my invention is to provide stop devices for determining the extent of backward and forward rotation to be given the platen for the introduction and proper positioning of each new invoice sheet in billing work.

A further object of my invention is to provide devices which are in the nature of billing attaclnnents that may be app led to existing forms of typewriting machines witl'iout the ecessity of changing the structural features interfering with the ordinary operation of said machines for general work and by the use of which billing attachments condensed record billing work may be readily done on the machine.

A still further object of my invention is to provide devices of the character specified which are adapted for use, without modification or change, to machines -mploying line spacing ratchet wheels having teeth i-vhich are spaced different distances apart.

Another object of my invention is to provide devices of the character specified which may be employed for billing purposes without taxing the mind of the operator in setting and operating the device.

To the above and other ends which will be hereinafter more fully described r invention consists of the features of construction, arrangements of parts and combinations of devices to be hereinafter described and claimed.

In the accompanying drawings wherein like reference characters indicate corresponding parts in the different views, Fi ure 1 is a fragmentar side elevation with parts sectioned away showing the upper portion of one form of typewriting machine with my invention applied thereto. Fig. 2 is a frag- A nientary top plan View of the same. Fig. 3 is an enlarged, detail, fragmentary, vertical, sectional view showing the billing attachments. Figs. 4, 5, 6 and 7 are detail face views of different parts of the billing device; Fig. 5 showing the friction device before it is bent up into the shape in which it is employed in the machine.

I have shown my invention applied to a No. 6 Remington typewriting machine though it should be understood that the invention. is capable of general application and may be employed in other styles of machines and in fact is readily adapted to various forms of typewriting machines employing cylindrical platens.

The top plate 1 of the machine is provided with upwardly extending posts 2 which support a traverse rod 3 with which supporting and guide rollers 4 cooperate; the rollers being carried by a carriage truck 5 of the usual construction employed. in the No. 6 Remington machine. l he rear of a platen frame 6 is pivoted at 7 to links 8 which in turn are pivoted at 9 to the truck, whereas, the front of the platen frame carries a roller l that cooperates with a shift rail in the usual manner. 'lhe platen frame supports the usual cylindrical or rotary platen 10 provided with a platen shaft 11 which is secured thereto in the usual manner and is supported in bearing openings in the side bars of the platen frame and projects through said bearings be yond the frame, as indicated in Fig. 3. The platen is provided at the right-hand end thereof with the usual line spacing ratchet wheel 12 and cooperating line spacing pawl 13 pivoted at 14 to an upright arm 15 of a line spacing lever 16 pivoted at 17 to a bracket arm 18 secured to the platen frame. The platen frame carries the usual standard or upwardly projecting lug 19 which constitutes a support for the inwardly projecting stop pin 20 with which the line sp acing pawl cooperates to prevent an overthrow of the platen. A stop 21 which is in the form of I an angular arm is secured to the upright bracket or lug 19 by a screw 22 that forms part of the stop pin 20. The engaging portion of the stop 21 projects to the right of the platen frame, as shown in Fig. 3, where it extends into the path of cooperating stops, as will hereinafter more clearly appear.

Two disks 23, 24 are coextensive in size and are arranged side by side and secured in clamping or frictional engagement by a finger 25 formed integral with the disk or plate 23 and bent over the contiguous plate 24 so as to cooperate therewith and to clamp the two plates in frictional engagement. fhe disk 23 is provided with an integral stop 26 which projects from the periphery thereof. A. like stop 27 projects from the periphery of the disk 24 and both of these stops are adapted to cooperate with the fixed. stop 21 carried by the platen frame and which extends into the path of the stops 26 and 27. A sheet metal thimble 28 is seated in central openings in the disks 23 and 24 and constitutes a bearing for said disks. The thimble is preferably turned in at its edges 29 toward the disks so as to maintain them properly seated on the thimble and to exert a clamping pres sure thereon. The bore of the sleeve itself corresponds substantially to the diameter of the platen shaft 11 and is seated loosely thereon outside of the platen frame. A washer 30 is interposed between the sleeve 28 and the outside of the platen frame to form a bearing for one side of the sleeve. 'l his washer is shown in detail in Fig. 4, from which it will be seen that the bore 31 thereof has a flattened side wall 32 which cooperates with a corresponding flattened wall 33 on the platen shaft in order to lock the washer to turn with the platen shaft.

A. finger wheel 34 is secured by a set screw 35 to the right-hand end of the platen. shaft and interposed between the finger wheel and the disk 23 is a spring friction device 36 preferably formed of a single piece of spring metal and bent into U-shape in cross-section with an opening 37 which receives the platen shaft and also an opening 38 that receives the stem 39 on the finger wheel 34. 'l he construction of this spring is such that it exerts an outward pressure against a portion 40 on the linger wheel and an inward. pressure against the disk 23. lhe effect of this friction device is to cause the disks 23 and 24 with the stops carried thereby to turn with the platen and to afford an independent rotation of the platen when either of the stops 26 and 27 is brought into cooperation with the fixed stop 21. The friction exerted by the device 36, is, however, insufficient to overcome the greater friction maintained between the two disks 23 and 24, so that the disks and the stopscarried thereby will be maintained in the relative positions to which they are adjusted in setting the stops. In other words, the rotation of the platen will turn the disks 23 and 24 with the stops carried thereby in either a forward or backward direction without affecting the relative adjustment of the stops 26 and 27 and when either of these stops is brought into contact with the fixed stop 21, the disks will be held against further movement in the direction in which the platen is being turned, while the platen may be turned independently of the stop devices.

Under one mode of operating the devices for condensed record work the stop 26 will first be adjusted to a position. where it is brought into contact with the fixed stop 21. The invoice, condensed record sheet and carbon are then introduced, with the leading edges thereof together, at or within the bight between the main feed rollers 41 and the platen and the platen will be turned in the direction of its line feed movement by one of the linger wheels of the platen until the point on the invoice where the first line of writing is to appear is brought to the printing line. the first instance by the operator turning back the platen frame and observing whenthe point on the invoice sheet where the first line of writing is to appear reaches the printing line. During this turning movement of the platen the stop 26 will be turned with the platen, through the friction device 36, from the position shown in Fig. 1 where it engages the fixed stop 21, to a position which it may he assumed corresponds substantially to the position of the stop 27 in Fig. 1. Vfith the stop 26 held by the operator in the position to which it has been automatically moved by the platen during the feed movement just described, an adjustment of the stop 27 in the direction of the arrow in Fig. 1 relatively to the stop 26 is effected to bring the stop 27. into contact with the fixed stop 21. 55 nch relative adjustment between the stops would, it may be assumed, leave them in the relation shown in Fig. 1, the difference being that the stop 27 will be in contact with the fixed stop 21 and the stop 26 will be in a position corresponding substantially to the position of the stop 27 shown in said figure. The stops having been set in the manner stated, the operator may fill in the invoice and as the invoice is being written and the platen is rotated in the direction of its line feed movement, the stop 27 will be maintained in contact with the fixed stop 21 through. the frictional connection between the stop devices and the platen. When the operator has written the invoice, say two line space movements of the platen may be given in order to produce a space between the last line of the invoice just reproduced on the condensed record sheet and the first line of the next invoice to be reproduced through the carbon on the condensed reoorc sheet. When this line spacing movement has been effected the operator will turn the platen baokwardly carrying the stops 26 and 27 with it until the stop 26 has, through the frictional devices, been brought into contact with the fixed stop 21, as shown in Fig. 1, the operator ceasing the turning movement when the contact takes This may be determined in place. This backward rotation of the platen from position where the stop 27 contacts with the fixed stop to a position where the stop 26 is brought into contact with th fixed. stop determin s or defines the extent of backward rotation to be given to the platen in orl r to insert a new invoice. This is done Without removing from the machine the invoice sheet which has just been written. The second invoice sheet being inserted as before described, the platen. is rotated forwardly until the stop 27 is again. brought into contact with the fixed stop 21 andv the second invoice sho will be in proper position to receive the st line of writing, and this iinc will be reproduced on the condensed record sheet two line spaces from the last line written or reproduced from the previously written invoice on the condensed record sheet. The imprint on the condensed record sheet is produced through the two bill sheets and the carbon sheet. l /hen the second invoice has been written, two line space movements will be given to the platen. The plat-en will then be turned back until the stop 26 is brought into contact with the fixed stop 2i. when a third invoice may be inserted before and the platen turned forward until the stop 27 is brougl. into ontact with the fmed stop 2i, when this third invoice may be written and reproduced on the cond onsed record sheet as before and any number of invoices on bill sheets of a given. size may be written by foll the operation described. By the time the third. invoice has been completed, where invoice sheets of ordinarv size are used, the first written invoice sheet will he fed out of the nachine or be fed to a position where it can he readily removed from the machine without disturb ing the other invoice sheets, the condensed record sheet, or the carhon sheet. hen the condensed record sheet has been, filied it is merely necessary to introduce a new condensed record sheet, carbon sheet and invoice sheet into the machine, when the stop 26 is located in cont ct with the fixed stop 21 and to turn the platen forwardly until the first printing line is reached, as d e terminco by the contact of the stop 27 with the fixed stop 21 as before. A single setting of the steps 26 and 27 with relation to each other answers indefinitely for bill or invoice sheets of a given size and a further setting of hose parts is unnecessary until bill or invoice sheets of different size are to be employed.

if desired, a "lead of "he i'irst invoice sheet introduced with each carlaon and record sheet may he given in order that the first line written on the first invoice sheet may he reproduced through the carbon as near the leading edge of the record sheet as may be desired, and if desired each bill sheet may be removed from the machine after it is.

written without disturhing the carhon or record shoot.

it will he seen from the foregoing descr1p- 'tion that the operation of the machine for condensed record work, after the steps 26 and 27 have een set, merely consists in a forward and bacrrward rotation of the platen to given extents as determined by the contact of the stops 26 and with the fixed stop 21 and Ly effecting a two line space i ioveinent of the platen before each backward rotation "hereof that the steps 26 and 27 are combined with means such as the friction device 36 for effecting a movement of said stops relatively to the stop 21 hy a backward and forward rotation of the platen; that, nevertheless, said means afford a rotation of the platen independently of the stops 26 and 27 and that the extent of each backward and forward rotation of the platen, for the introduction and proper positioning of a new invoice, is determined by the stops 21, 26 and 27. It will he understood, furthermore, that there is no burden on the mind of the operator in operating the device and that no mental calculations are required to effect a setting of parts or to effect "condensed record Work with the aid of these billing attachments. Furthermore, it will he understood that the stops 26 and 27 are capahie of being set by their frictional connecting means to correspond. to any Line space position that may he attained, irrespective of the character of the spacing of the teeth of the line spacing ratchet wheel. Then, again, it will lie seen that by locating the stop devices outside of the platen frame I am enabled to readily apply them to existing forms of typewriting machines Without modifying the structural features of such machines, and that by my invention I have provided simple, cheap and efficient billing devices which are easy of operation and cannot become easily deranged or hrolren.

During ordinary operation of the machine the stop devices do not interfere with the backward and forward. rotation of the platen. The additional friction which maybe exerted ls-y the stop devices against the turning movement of the platen is so slight as to not li e appreciable in the ordinary operation of machine.

Various changes may be made Without departing from the spirit of my invention.
